Start by Watching, Not Digging

An overgrown allotment in March can feel overwhelming, and the temptation is to hire a rotavator and blitz the whole thing in a weekend. Resist that urge. Spend your first fortnight simply watching the plot. Note which end catches the morning sun and which stays damp until midday, where puddles linger after rain, and where the previous tenant's rhubarb is still stubbornly alive. These observations will shape everything you do later.

Walk the site boundaries too. Find out where the communal water trough is, whether there is a hosepipe ban in summer, and how far you must carry a full watering can. Introduce yourself to the site secretary and a couple of neighbours — allotment holders are famously generous with spare seedlings, tools and advice, and they will know which corners of your plot flood and which fences blow down in a gale.

• Check your tenancy agreement for rules on sheds, bonfires, fruit trees and hedges.
• Find out whether the site has a shop, manure deliveries or a communal skip.
• Photograph the plot from the same spot each month — it is astonishing how much you forget.

Assess Your Soil Properly

Before ordering seeds, get your hands dirty. Dig a spade's depth in three or four spots and squeeze a handful of moist soil. If it forms a smooth ribbon that holds together, you have clay; if it crumbles and feels gritty, it is sandy; if it is silky and slippery, you are on silt. Most British plots are clay or clay-loam, which is nutrient-rich but cold and slow to drain in winter and rock-hard in August.

Test the pH with a cheap kit from a garden centre. Most vegetables prefer around 6.5, slightly acid. Brassicas, however, will thank you for lime if your soil is below 6, while potatoes dislike it — hence the old rule of liming one year and manuring the next, never both at once.

Then dig a trial pit a spade deep to check for a compacted pan or a buried layer of builder's rubble. If drainage is dire, raised beds may be the answer. Otherwise, work in well-rotted manure or garden compost each autumn and let the worms do the rest.

Plan Your Beds Before You Plant

Mark out beds no wider than 1.2 metres — that way you can reach the middle from either side without standing on the soil. Paths of 45 to 60 centimetres allow a wheelbarrow through comfortably. Beds can be any length, but keep them manageable: four beds of 3 by 1.2 metres is a far better start than one enormous patch.

If you are on heavy clay or a sloping site, timber-edged raised beds are worth the outlay. On lighter soil, open-ground beds with mown grass paths are cheap and quick. Either way, group crops by family so you can rotate them:

• Legumes: peas, broad beans, runner beans — fix nitrogen and improve the soil.
• Brassicas: cabbages, kale, sprouts — hungry, lime-loving and vulnerable to clubroot.
• Roots: carrots, parsnips, beetroot — prefer fresh ground that was manured the previous year.
• Potatoes and alliums: potatoes break up new ground; onions and leeks follow happily.

Sketch the plan on paper, pencil in your rotation, and accept that it will change. Planning is a guide, not a contract.

Winning the Weed War in Year One

Weeds are the real test of a new allotmenteer. Perennial thugs — couch grass, bindweed, ground elder and mare's tail — cannot be hoed away; every chopped fragment regrows. Annual weeds, by contrast, are shallow-rooted and die quickly under a hoe or a mulch.

Identify which you have before choosing tactics. On a badly infested plot, cover at least half the ground with black polythene, old carpet or thick cardboard weighted with manure for a full season. Light-starved roots weaken and die. Where you must plant immediately, dig out perennials by fork, following every white root, and sow a green manure such as field beans or grazing rye on the cleared ground to smother regrowth.

• Hoe on a dry, sunny morning so severed weeds wither on the surface.
• Never let annual weeds set seed — one fat hen can drop thousands.
• Mulch with compost or straw to bury the seed bank.
• Weed little and often; twenty minutes twice a week beats a punishing Sunday.

What to Grow in Your First Season

Be realistic. A half-plot is plenty for a beginner, and you can grow a surprising amount in it. Start with forgiving crops that reward neglect: courgettes, runner beans, potatoes, chard, beetroot, salad leaves and autumn-planted garlic. Buy seedlings for anything fiddly — brassicas and leeks are far easier raised at home in modules than sown direct into a weedy plot.

Sow little and often rather than one giant row. A metre of salad sown every three weeks will feed you from May to October; three metres sown at once will glut you for a fortnight and then bolt. Keep a notebook of sowing dates and results — your second year will be twice as productive because of it.

Settling Into the Rhythm

Install a water butt early, as mains water is a long walk away. Keep a sharp spade, a fork, a hoe and a hand trowel in a locked shed, and leave a bucket for weeds. Visit little and often rather than in heroic weekend bursts; allotments reward steady attention. By the end of your first season you will have a weeded patch, a compost heap and a stack of hard-won knowledge — which is exactly what a good allotment is built on.
